Ontario problem patterns
Common Subterranean Termite Treatment Problems in Ontario
The issues we fix most for Ontario homeowners, and why they happen here.
01
Shelter tubes climbing foundation walls
Why it happens: San Bernardino County's seasonal winter rainfall leaves soil damp around foundations, creating termites a perfect highway into the home. Mild warm, dry summers accelerates their tunneling.
Our approach: We locate every mud tube and follow it back to the colony. Then we apply a precision soil treatment to cut off the entry point.
02
Soft or sagging wood near the foundation
Why it happens: Ontario's damp mild, wet winters lets moisture to build up in crawl spaces, drawing subterranean termites. Timber remains wet and becomes easy pickings.
Our approach: We inspect the crawl space and pinpoint affected members. Then, we use a wood treatment and recommend ventilation fixes to prevent recurring problems.
03
Flying termites showing up inside or around lights
Why it happens: After winter rains, subterranean termites swarm to launch new colonies. Ontario's mild warm, dry summers triggers these flights, and they frequently end up in homes.
Our approach: We confirm the species and find the source colony. Then we use a colony elimination that stops the infestation and blocks future swarms.
04
Cracked paint or uneven surfaces masking termite damage
Why it happens: Subterranean termites eat wood from the inside out, leaving a papery layer that looks fine. Ontario properties with foundation issues are especially vulnerable.
Our approach: We employ moisture meters and thermal imaging to find the damage. Then we repair the source and coordinate on wood repairs.
